Specification of Letters Patent.

Patented Mar. 25, 1919.

Application filed June 2, 1917. Serial No. 172,417.

To all whom it may concern:

Be it known that I, /VILLIAM H. HAIGH'I', a citizen of the United States, resident of Northfield, in the county of Rice and State of Minnesota, have invented certain new and useful Improvements in Knockdown Furniture, of which the following is a specification.

The object of this invention is to provide a piece of furniture of simple and inexpensive construction, and one which may be easily assembled or taken apart for shipping or packing.

A further object is to provide a piece of furniture which may be easily adjusted to various positions to suit the comfort of the user.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in the Various constructions and combinations all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specifi ation,

Figure 1 is a side elevation of the frame, set at a height to form a bed or cot, the dotted lines showing how the same frame may be adjusted to form a hammock,

Fig. 2 is a plan view of the same frame as shown in Fig. 1, with the fabric broken Fig. 3 is a design of the same style of frame in elevation showing how it may be changed to form a chair,

Fig. 4 shows the device'a'djusted to form a reclining chair,

Fig. 5 is a sectional view on the line 5, 5 of Fig. 4,

Fig. 6 is detail view showing the means for fastening the corners of the frame,

Fig. 7 is a sectional view on the line 7, 7, of Fig. 1.

In the drawings, 2 represents the principal side members forming the frame, there being two of the same on each of the opposite sides. 3 represents the bearing cross bars and i and 5 respectively the foot and top bars connecting the two sides of the frame together. 6 is a clamp provided for securing the cross members of the frame from slipping and for otherwisestrengthening the joint. 7 shows the fabric covering forming the seat or mattress and 8 denotes the terminating hem ofthe same, inclosing a stretcher.

It will be observed that I have made a: departure from the common method of securing the cross members of the frame, in that I have eliminated the usual pin, each of the end sections being secured together and independent of the other, and being adapted to slip to and from each other freely, and always having a proper bearing, the effect of this movement being to raise or lower the frame as desired.

By having this bearing the whole frame is greatly strengthened, and increased weight on the seat serves to make it more rigid, the fact that the bearing bars extend across the frame from side to side being an added factor to its rigidity.

As will be seen. by reference to Fig 1 the bearing bars are set upon the top of the crossed members. In the operation of changing from a cot or couch to a hammock position, the sides of the upper angle are lengthened, and in the case of the reclining modification of the chair as exhibited in Fig. l. the bearing bars being on the under side of the crossed members, it will be observed that the same operation produces a contrary effect, as the sides of the angle are shortened, these effects being desirable in either case.

As it is my purpose to use a choice of many different methods of fastening the cross bars to the side members I make only one showing of this feature, but in any case, whether I use plain belts with thumb nuts, a pin and so"ket device, angle plates secured with belts, or other means, I intend to make the connection so that the said members may be interchangeable to either the top or bottom of the braces.

I also propose to provide multiple holes in the crossed side braces so that when desirable. either-of the bearing bars may be adjusted to a different position, relative to the ends, so that the two ends of the frame may be made of different heights.

While there may always be considerable binding weight on the crossed joint of the frame, the added body weight on the covering tends to raise the extreme upper ends of the frame, the draft being toward the joint, and in the case as shown in Fig. 1 it becomes necessary to provide strong clamps to prevent the joint from slipping. Such a (lamp is shown in detail in Fig. 7. This is of wood, and long enough to straddle the joint when the frame is in any position, the

"binding being made simply turning thumb nuts on the securing bolts at. each an r a r In the modified construction as shown in r Figs. 3 and 4 so'strong a clamp is unnecessary and if anyitfused 1t W-lll be more nearly I automatic.

The covering 7 may be of any desirable fabrics, and; either as a Whole or in concentrated strands, runnlngover the end or ends of the fram'eyto the 'en'd that the length and tension may be a'djusted to' the frame as desiredif H I makeno clalmvasto the fastenmg, as the choice of several means may be used.

.VVhe'n desirable, as in its use inhospitals' for Wounded; the covering may be loose from :the frame and adjustable at both ends, so

it maybe easily and quickly changed When soiled or infected. a a

It is my desire to provide simple and comparatively inexpensive device that may be quickl fp'ut' together'or taken apart,

closed up and setasi'de when not in use, making a small and compact bundle for sirable couch that may be raised to a bed at any height, jor altered to a hammock or.

reclining chain, an of the same general constru'ot o'n. s
